New Pirkle-type chiral stationary phases with mixed pi-acceptor and pi-donor properties

All CSPs contain a strong p-acidic N-3, 5-dinitrobenzoyl group, which is expected to interact with p-basic aromatic derivatives, and p-basic naphthyl, 3, 5-dimethylphenyl, anthryl or pyridyl group, which can be utilized for interactions with the p-acidic racemic analytes. The chiral selector is covalently bound at silica surface with the spacer who is placed behind the chiral center, so that in stacionary phase the chiral hole of selector is ideally open for analytes approach.
